Abstract: A method for providing light to a Cannabis plant is disclosed. The method comprises, during a first time period of a flowering stage of the Cannabis plant, the first time period being one or more days, controlling a horticultural illumination system to provide horticulture light to the Cannabis plant such that the Cannabis plant is exposed to a first photoperiod. The method further comprises, thereafter, during a second time period of the flowering stage of the Cannabis plant, the second time period being one or more days, controlling the horticultural illumination system to provide horticulture light to the Cannabis plant such that the Cannabis plant is exposed to a second photoperiod. Herein, the second photoperiod is longer than the first photoperiod.
